SELF-ACTING CHEESE-PRESS.

Specification of Letters Patent No.

To all whom imag concern.'

Be it known that I, JOHN MARTIN, J r., of Medina, in the county of Medina and State of Ohio, have invented a new and useful Improvement in Machines for Pressing Cheese, which is described as follows, reference being had to the annexed drawings of the same, making part of this specification.

Figure l is a side elevation of the machine, ready for operation. Fig. 2 is a top view of the lower block, showing the lower series of pulleys.

Similar letters refer to corresponding parts.

` This machine consists of two circular blocks of wood A, B, one arranged above the other, each containing a series of six or more pulleys C, arranged at equal distances apart, in countersinks or mortises made in the upper surface c-f the lower block, and the lower surface of the upper block, and near the peripheries of the same. A center stock or piston D is attached to the upper block, which extends downward through an opening in the center of the lower block to the cheese board below, where the pressure is applied.

The blocks A, B are about ten inches in diameter and the pulleys two inches, or of sufficient diameter when placed around parallel with and three quarters of an inch within the periphery, as to ll the circle with the twelve or whole number of pulleys; but there are only siX pulleys in each of the blocks, and consequently there are` spaces equal to the diameters of the pulleys, between each of them.

The windlass E, which suspends and operates the machine, turns in a frame secured to the side of the room, a sutlicient distance above the press.

.en aperture a is made in the center of the upper block which extends through the center stock or piston D in a vertical direction, and communicates with a space or mortise m formed in the lower block, containing a pulley Gr, larger thanthose mentioned above. This aperture o is for the admission of the rope H, which being` `fastened to the windlass above, passes down through the aperture a, into the mortise and under the large pulley G, up through an opening in the lower block to one of the small pulleys C in the upper block, and after passing over that 8,840, dated November 26, 1844.

pulley extends back to a similar pulley in the lower block and passes under it, thence over a pulley in the upper block, thence under a pulley in the lower block. It so continues from the upper to the lower block and from the lower to the upper block, around`the circle of pulleys until it arrives at the end of the system, where the-end is secured to a pin 29 inserted in the lower block, near the aperture through which the rope passes from the large pulley to the pulley in the upper block.

Two strong rollers I are attached to the bottom of the frame of the press, on which the cheese board rests. facilitate the operation of sliding the cheese in and out, as may be required. i

To put the press in operation,'the rope, K, attached to top block, is fastenedV by a loop to a hook on the windlass, the crank L, is then turned until the center stock or piston D, leaves a space below, for sliding in the cheese; the key M is then forced out- `and the upper and lowerblocks, are held asunder until the cheese is put in the press. rIhe key is then drawn in, and disengaged from the crank L, and the center stock or piston D, drops on the cheese; the rope K, is then let loose from the hook on the windlass and the suspending rope H which is fastened to the windlass, is coiled on the windlass, until the press is raised a sufficient height from the floor, or until the top block reaches the windlass. rIhe key M, is then forced out and the gage rope, N, which is slung at the other end of the windlass, and passes around the windlass, in an opposite direction to the suspending rope, is hooked into the loop in the -upper block,A A; this removes half the power from the press, by leaving only half the weight on the pulleys, and preserves the richness of the cheese,

which the whole power, would if applied,

press o-ut. After remaining suspended on the gage rope N as long as necessary, the pressis again raised by the windlass, the key slipped out, and the gage rope removed. W'hen time to turn the cheese, dis- They also serve to engage the key from the crank, and gradp key-and after turning the cheese slide back the key, let fall the upper block, and again What I claim as my invention and'which y turn the Windlass, and raise the press, &c.

The press is Atwo and a half feet in height, and about two feet Wide at the bottom; therefore the small compass which the machine occupies is another of its advantages.

The press may be constructed with more or less pulleys, and of any size to suit the convenience of the dairyman, but for common use, I Would recommend the proportions described above,4

I desire to secure by Letters Patent, is-

The before described combination 'of block or frame B of the self acting press With the piston A, D, cord I-I pulleys C, and Windlass E suspended and operating in the manner and for the purpose set forth.
